PayDelete

The DeadDelete Plugin for WordPress allows developers to make removing outdated content from their sites easy by allowing users to click a button that checks source URLs for 404 or 301 status codes. If the source returns a 404 the post is trashed. The same is true in cases of 301s if the final destination is known to be a destination for missing content.
DeadDelete is designed primarily for aggregators that copy content from other websites with source attribution links included. It is ideal for RSS based auto-blogs that include a large amount of content from other sources. With DeadDelete a user can click a button when they notice that an article is based on a source that no longer exists and remove your copy so that you don’t have to.
